Over the past several years, shipping lithium batteries via air freight has been serious business and it requires significant investment from any company who manufacturer custom battery packs. Not only do companies need to make sure that battery packs are shipped properly without delays, but also for the safety of the public. As of April 1, 2016 international regulations applicable to air shipments of lithium batteries have changed yet again and will require that all companies that manufacture and ship batteries continue to invest to stay ahead of the requirements.

Understanding the environment which your assembly will be used in may determine whether or not your application will require shielded cables. Applications where cable assemblies are utilized are often electrically noisy, industrial environments, where factories can create interference within cables. If your cables at at risk of electrical noise interference, shielded cables can greatly improve the performance of your equipment.

Essential to any flex or rigid-flex printed circuit board (PCB) contruction is validation that your flex PCB design will meet your mechanical bend requirements. Minimum flex bend radius requirements were put in place so your design won't exceed the physical capabilities of copper circuitry, which would result in failed parts, long term reliability concerns, and several giant headaches.

There was a time when “Made in China” was synonymous with cheaper, poor quality products. "Buyer beware" was the common theme associated with outsourcing to any Asian PCB manufacturers. So how did Epec approach this challenge and succeed? It was by managing quality through intense auditing, training, and qualification. Epec understood at a very early stage that first-class quality products from Asian manufacturers would require consistent presence, training, and auditing.

Designers and manufacturers of silicone rubber keypads understand they are used for a wide range of industries and applications while needing to withstand heavy usage. Keypads are used extensively in both consumer and industrial electronic products as a low cost and reliable switching solution. In specific applications rubber keypads may be used in harsh outdoor environments that must withstand hundreds of actuations on a daily basis.

As a necessary component in countless applications, custom designed cable assemblies have a major impact on the cost, and therefore the profitability, of any project. Designing a cable assembly that meets both environmental and electrical demands, while keeping costs low, can be a challenging task.

This blog post is intended to reinforce the design support we offer at Epec for our flex and rigid-flex PCBs. Technical design and engineering is one of our core foundations which allow us to best help our customers meet their product requirements. Within the post, we'll cover design areas that require special consideration.

Cleanliness of bare circuit boards increases in importance with advances in PCB technology that continue to decrease conductor spacing. Inorganic contamination within printed circuit board fabrication can lead to electrochemical migration. Electrochemical migration is the dissolution and movement of metal ions in presence of electric potential, which results in the growth of dendritic structures between anode and cathode. These dendritic growths, which were minimal over periods of time, were not a concern of "yesterdays" bare boards.

As a leader in user interface technology, we frequently get asked the question, "What kind of user interface is the best option for my application?" User interface, or Human Machine Interface (HMI), assembly designs are dependent on the application, housing, and the environment they will be used in. Choosing the right option and material is a key component.
